关于JAVA远程获取XML的UTF-8中文乱码的问题！！
最近要远程获取的XML数据，而XML的编码方式问UTF-8，获取之后里面的中文全部是乱码，而获取GB2312编码的XML数据就能的到正确的数据！

Java code

public class XmlTransfer{  private String urlAddr;  private String xmlStr;  HttpURLConnection urlCon = null;  public XmlTransfer(String _urlAddr,String _xmlStr) {    this.urlAddr = _urlAddr;    this.xmlStr = _xmlStr;  }  public InputStream get() throws Exception  {    if(urlCon==null){urlCon=getUrlConnection();}    if(urlCon==null){throw new Exception("连接失败");}    PrintWriter out = new PrintWriter(urlCon.getOutputStream());       urlCon.disconnect();    InputStream fin1 = urlCon.getInputStream();    return fin1;  }  private HttpURLConnection getUrlConnection(){    try{      URL url = new URL(urlAddr);      URLConnection conn = url.openConnection();      urlCon = (HttpURLConnection)conn;      urlCon.setRequestProperty("Content-type", "text/html;charset=utf-8");      urlCon.setDoOutput(true);      urlCon.setRequestMethod("GET");      urlCon.setUseCaches(false);    }    catch (MalformedURLException mex) {      mex.printStackTrace();    }    catch (ProtocolException pex) {      pex.printStackTrace();    }    catch (IOException iex) {      iex.printStackTrace();    }    return urlCon;  }  public   String getHttp( String strURL ){      XmlTransfer xt=new XmlTransfer(strURL,"");      StringBuffer sb = new StringBuffer();      try{          InputStream is = xt.get();                    byte[] b = new byte[1024];          int iCount = 0;          while ((iCount = is.read(b)) > 0) {              sb.append(new String(b, 0, iCount));          }      }catch(Exception e){          sb.append("An error occurs in XmlTransfer.getHttp\n");          sb.append(e.getMessage());      }     return (sb.toString());  }    }

[解决办法]
这个不是取决于你的编码,而是取决于对方的编码格式

GB2312是两个字节存贮一个字符
而utf-8在c#中好像是3个字节

所以如果对方的xml是gb2312编码,而你采用uft-8编码
那么在读取的时候会将原本两个字节一组的字符强制以3个字节一组进行解码
结果可能就是乱码

总之就是对方的xml用什么编码格式编码,你就用什么编码格式进行解码,不是说简单的utf-8就行
之所以用utf-8,只是因为utf-8是大多数xml采用的编码格式而已

是这样的，我以前遇到过，你要进行转码的，转码就好了

Java code

StringBuffer temp = new StringBuffer();InputStream in = new BufferedInputStream(urlCon.getInputStream(););                Reader rd = new InputStreamReader(in,"UTF-8");                int c = 0;                while ((c = rd.read()) != -1) {                    temp.append((char) c);                }                in.close();temp.toString();//得到xml

你一个过滤器就ok!

package com.shop.filter;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;

public class EncodingFilter extends HttpServlet implements Filter {

   //Handle the passed-in FilterConfig
   public void init(FilterConfig filterConfig) throws ServletException {
       this.filterConfig = filterConfig;
   }

   //Process the request/response pair
   public void doFilter(ServletRequest request, ServletResponse response,
                        FilterChain filterChain) {
       try {
           System.out.println("这是一个过滤器.................................."); 
 
           HttpServletRequest hrequest=(HttpServletRequest)request;
           HttpServletResponse hresponse=(HttpServletResponse)response;
           String strUri=hrequest.getRequestURI();
           if(strUri.endsWith("login.jsp") && strUri.endsWith("doLogin.jsp")){
               HttpSession session=hrequest.getSession();
               if(session.getAttribute("loginName")==null){
                   hresponse.sendRedirect("login.jsp");
                   return;
               }
           }
           request.setCharacterEncoding("GBK");//字符编码
           filterChain.doFilter(request, response);//表示过
       } catch (ServletException sx) {
           filterConfig.getServletContext().log(sx.getMessage());
       } catch (IOException iox) {
           filterConfig.getServletContext().log(iox.getMessage());
       }
   }

   //Clean up resources
   public void destroy() {
   }
}
